RDF4J 5.0.0 Milestone 1

Tue, Aug 8, 2023

Milestone number 1 of the upcoming 5.0.0 release of RDF4J is now available for download.

This first milestone focuses on removing deprecated code with the largest change being the removal of the Iteration interface in favour of using the CloseableIteration interface instead. The CloseableIteration has also been simplified by removing support for specifying checked exceptions using Java generics.

This milestone build is not yet feature-complete, but we are putting it out to receive early feedback on all the improvements we have put in.


Eclipse RDF4J™ is a powerful Java framework for processing and handling RDF data. This includes creating, parsing, scalable storage, reasoning and querying with RDF and Linked Data. It offers an easy-to-use API that can be connected to all leading RDF database solutions. It allows you to connect with SPARQL endpoints and create applications that leverage the power of linked data and Semantic Web.
